Abstract: The North-East Region of China consists of three provinces and three districts(Meng)of Inner Mongolia Autonomous Region.There are rich coal resources, making up 9% of the total coal resources of China,and kerogen resources are also rich there.The output of 1979 was more than 110 million tons,making up about 18% of the total coal output of China.Now coal consumption is about 70% of the total consumption of various energy constituents in this region.The minerogenetic epoches of the coal and kerogen are mainly in the Carboniferous and Permian period, the Jurassic and Cretaceous period,and Tertiary period.The coal generated in the two former periods is mainly bituminous coal,and in the latter is mainly brown coal. At present,there are two important problems on the production of coal industry here.fIrstly,the distribution of coal industry is not in equilibrium,most of them concentrates in the east part,but coal consumption concentrates in the middle industrial region.So,speedy development of several big brown coal field in the west part should be carried out,and coal or electric current should be sent to the middle part region.Secondary,the comprehensive and rational utilization of coal should be considered.Now about 80% of the coal consumed is used in direct burning in this region.The utilization coefficient is only about 25% of the heat energy of coal.So,it is very important to pay attention to coal screening,productive quality improving,and reducing of inefficient transport and discharge of pollutant.
